Al R-COOLING REFRIGERATOR.

i SPECIFICATION forming part of Letters Patent No. 296,071, dated April 1, 1884,

` Application filed January 24, 1884. (No model.)

To all whom, it may concern:

Be it known that I, DAVID SANDnRsoN, of Ottawa, LaV Salle county, Illinois, have invented a new and Improved Air-Cooling Re- 5 frigerator,` of which the following is a full,

clear, and exact description.

The object of my invention is to provide certain new and useful improvements in the ice-` beds of refrigerators, whereby,` the air can be caused to circulate well around the ice in the 4ice-rack, and thus cool the air in the room in which the refrigerator is placed. The invention consists of the combinations of parts and their construction, substantially as hereinafter fully set forth, and pointed out in the claims. Y .A

Reference isto be had tolthe accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure 1 is a longitudinal sectional elevation of a refrigerator provided with my im- I provements. Fig. 2 is a cross sectional elevation of the same on the line fr x, Fig. l.

The ice-bed A in the refrigerator B is' made hopper-shaped-that is, it is inclined from the sides and ends of the refrigerator to an oblong .opening or slot, C, formed in the said ice-bed. A gutter, D, is formed on the ice-bed around the slot or opening, which gutter is provided with an outlet-pipe, E. The ice-rack F,` on which the ice is placed, is placed on the icebed Ain the manner shown, and to the under side of the rack` a curved metal plate, G, is fastened, the said plate being curved`downward from the longitudinal middle axis of the The water that y, drips from the ice through the rack F flows `down the curved plate G upon the icelbed A, and downthe inclined sides of the same into the gutter D. A slot or narrow oblong opening, R, in the upper sides of the refrigerator, near the top, acts as an outlet or vent for the warm impure air that pervades the upper 45 `portion of the cooling-room in which the refrigeratoris placed, allowing thisair to pass plate toward both side edges.

in upon the ice on the rack, thereby causing the impurities the air contains to be deposited thereon and pass 0E through the'meltage-water `by pipe E, while the air, being refreshed and 5o purified, sinks by its own weight downward through the slats and hopper-shaped ice-bed, and is diffused over the cooling-room through slot C on the under sideof the ice-bed, thus producing a cold dry atmosphere,.free from 55 moisture and impurities, and thereby automatically serving as a ventilator by its own natural action. The space between the icerack and the ice-bed permits of a thorough circulation of the air.

The above-described ice-bed can be placed in any refrigerator, large or small.` By means of it the air in a room can be cooled and be kept perfectly dry and pure Without the use of a ventilator, thus giving the cooling-room 65 in which it is placed a lower temperature. Having thus described my invention, I claim as new and desire to secure by Letters Patent- `,1. Ina refrigerator, the ice-rack having the 7o curved plate or deflector affixed at about its central upper vportion to the under side of said rack, in combination with the hopper-shaped ice-bed having a centra-l oblong air-passage in its lower convergent portion, substantially 7 5 as and for the purpose set forth.

2. In a refrigerator, the ice-rack having the curved plate or deiiector affixed at about its central upper portion to the under side of said rack, and the hopper-shapedice-bed having 8o a central oblongair-passage and a drip-gutter around said` passage, incombination with the case or inclosure having air-passages in its upper portion, the tube forming the ice-bed air-passage extending through the bottom of 8 5 said case or inclosure, substantially as and for the purpose set forth.
